I like the "redundant" sentence. I like the _Unsigned idea, but there are lots of old files "in the wild" that don't have that attribute.

This raises another question in my mind. To what extent does the current version of the document need to give homage to old usages? If your file says it uses CF 1.5, I wouldn't expect it to follow CF 1.7. So does the CF 1.7 or 1.8 document need to contain "grandfather" language (things that used to be, or not be, but that are different in the current version)?

Grace and peace,

Jim

lookin at the NUG, how about saying:

In file types that don't offer native support for unsigned types,
integer or byte variables that are to be interpreted as unsigned must
have the attribute _Unsigned = "true".

    LGTM.

        "One byte numeric data should be stored using the byte

        or unsigned byte data type."

        It too is copied from CF 1.7, and I think its intent was to tell
        people to store 1-byte numeric data as type byte not type char.
        With that rationale, if the sentence was in 1.7 then
        it should probably be in 1.8,


    yup --it's clear to me, and not annoyingly redundant.

    The truth is that char type IS used a lot on old C code for
    numeric data.

        although I'll go with
        the consensus.
